SAT Question 388b45aa: Transitions answer and explanation

Choice B is incorrect. This choice uses an exemplification transition, which doesn’t make sense here. This sentence is describing where the work of coordinating Coordinated Universal Time takes place, not giving an example of the work described in the previous sentence.

Choice C is incorrect. This choice uses an exemplification transition, which doesn’t make sense here. This sentence is describing where the work of coordinating Coordinated Universal Time takes place, not giving an example of the work described in the previous sentence.

Choice D is incorrect. This choice uses a disagreement transition. But this sentence doesn’t disagree with the previous sentence. They both describe the work involved in calculating Coordinated Universal Time.
